The Obligation to Forbid Backbiting and Leaving the Gatherings of Those Who Do It

Question:
May Allah reward you with good, and may He do you good. You also say in another case: In the gatherings of my relatives and family, they do not refrain from talking about people, backbiting them, and mocking them. I am sitting with them and I dislike what they do, so I advise them, but they may not listen to me, and even if they do listen, they return to talking about people again. Sometimes I cannot do anything except leave the gathering, and I hate what they do in my heart. Am I a partner with them in this evil of theirs? Even though I hate it, and I was recently forced to isolate myself from people because of those sins. May Allah reward you with good.

Answer:
There is no doubt that backbiting is a forbidden matter and a major sin among the major sins. It is obligatory for you to advise these people and forbid them. If they do not comply and continue in backbiting, then it is not permissible for you to sit with them, because they are in a state of disobedience, and it is not permissible for you to sit with them, even if you dislike what they do. You must isolate yourself from their gathering so that you may be safe in your soul. Yes.
